This volume was prepared by Rahel Aichele while she was working at the ifo Institute. It was completed in December 2012 and accepted as a doctoral thesis by the Department of Economics at the University of Munich. It includes five self-contained chapters. The chapters investigate how, in a...

Megacities already account for a major part of global energy-related CO2 emissions with a strong tendency to increase; hence, future climate policy has to put a special emphasis on reducing big cities' energy consumption, especially in a world, where global climate negotiations are deadlocked....

The 'Climate action and renewable energy package' proposed by the European Commission in the beginning of 2008 suggests auctioning as basic principle for allocation for the upcoming third trading phase of the EU Emissions Trading Scheme that runs from 2013 to 2020. Overall, it is estimated that...

The integration of climate policy concerns in other policy areas, where decisions are taken that determine greenhouse gas emissions, is a prerequisite for effectively mitigating climate change. There are particularly strong interlinkages between energy policy and climate policy as the major part...

In order to limit climate change the cross-cutting nature of climate policy needs to be recognised. Many climate-relevant decisions are taken in other policy areas with only little regard to climate change impacts. In order for climate policy to be successful it has to be integrated in decision...

If bioenergy has a less negative impact on the climate than fossil energy, it may be optimal to have a significant increase in the use of bioenergy over time. Due to the difference in the way the climate is affected by the two types of energy, the future time path of the use of bioenergy may be...

This paper introduces geoengineering into an optimal control model of climate change economics. Together with mitigation and adaptation, carbon and solar geoengineering span the universe of possible climate policies. Their wildly different characteristics have important implications for climate...

The Great Tôhoku-Earthquake and the following nuclear meltdown in Fukushima called the world's attention to Japans' energy and climate policy. Japan is one of the biggest emitters of greenhouses gases in the world and still far away from reaching its Kyoto target. Emissions trading systems have...

Technology policy is the most widespread form of climate policy and is often preferred over seemingly efficient carbon pricing. We propose a new explanation for this observation: gains that predominantly accrue to households with large capital assets and that influence majority decisions in...
